I'm with mlyvers, a boxer is an awesome dog. I've had 4 and IMO they bond stronger with their owners then most dogs. My male that I have now is about 4.5, his name is Evander, and he is my shadow. Most people think boxers are really hyper dogs, and while they can go outside an play an play, they can also be very calm. Every boxer I've had seems to mimic my mood and temperament. Evander is probably the best, most well behaved dog I've ever had. He is as friendly as can be but at the same time, he doesn't trust strangers and if I have someone new over to my house, he won't let them out of his sight. He will even follow them at a distance if they go to the bathroom an sit outside the door! Mostly he stays indoors and sits no more than 3 ft away from me at all times.
I traveled about 10 months out of the year for work during the first 3 years I had him so I sort of trained him to only listen to me and while it comes in handy, my fiancé hates it! He just refuses to listen to anyone but me. Anyway my rambling has gone on long enough, so to make a short story, boxers are great dogs. I wouldn't have any other breed.
